SANDAL.

Application filed December 22, 1919. Serial No.

To all whom it may concern:

Be it known that 1, CHARLES 0. Ron, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana have invented a certain new and useful Improvement in Sandals, of which the following is a full, clear, concise, and exact description, reference being had to the accompanyin drawings, forming a part of this specification.

My invention relates to sandals and more particularly to'a sandal which is adapted to be worn with boots or shoes in order to protect the soles thereof and to provide a roughened walking surface which will enable the user to walk over rough or slippery surfaces without danger of slipping or falling.

It is an object of my invention to provide a sandal of the character set forth which may be readily attached to the foot of the wearer exteriorly of the shoe and which is provided with a plurality of removable sharpened calks or spurs which may be replaced by others when they become worn out or dull.

It is a further object of the invention to provide a metallic sandal which ismade up of a plurality of yieldably or flexibly united sections which conform to the movements of foot of the user during walking movements.

It is a further object of the invention to provide readily detachable means for holding the removable calks or spurs in position, which readily detachable means bear at all times against the heads of the calks or spurs in order to hold them in projecting position on the sandal.

W'ith these and other objects in view which will be apparent from the detailed description of the sandal disclosed inthe drawings, I have shown one form wh h my invention may take which form :is the best known to me at the present time and is an improvement upon the sandal shown in my former Patent No.1,276,964 issued August 27, 1918. However it is to be understood that by this specification and the accompanying drawings I do not intend to limit myself to the specific construction disclosed as modifications in the specific structure may be required in the manufacture thereof or may occur to those skilled in this art. The real nature and scope of the invention disclosed the Specification of Letters Patent.

Patented Aug. 2, 1921.

is to be determined from the ed to this specification.

he same characters have been used :to designate the same parts throughout the several views of the drawings in which- Figure 1 is a side elevation .of my improved sandal shown attached toa shoe.

Fig. 2 is an exterior bottom plan view of the sandal looking upwardly in Fig. .1.

Fig. 3 is a longitudinal section taken on line 33 of Fig. 2.

Fig. at is a transverse section taken on line l4 of Fig. 2.

Fig. 5 is a transverse section taken on line 5-5 of Fig. 3.

Fig. 6 is a section through thetoe portion of the sandal taken on ,line 66 of Fig. 3.

Fig. 7 is a sectional view of one of the removable calks or spurs.

In the drawings the numeral 10 designates an ordinary shoe to which my improved sandal may be attached. My sandal is preferably made of metal and in order that it may be flexible it is made-ina pluralitybf yieldably or flexibly connected sections. The heel section '11 is formed from a single piece of metal which is stamped substantially into cup shape as shown in the drawings. The section 11 is of a size and shape to accommodate the heelportion of theshoe 10. .The heel portion is provided with openings 12 which will permit the escape of dirt or water that may get into the heel section. Each side of the=heel is provided with an ear 13 and the end of the-ear is bent into an eyelet 14. which forms a convenient attaching means for the strap :15 by means of which the heel section is secured to the foot of the wearer. The bottom of theheel section is provided with upwardly extending ribs 16 and 17 which ribs extend transversely of the heel section as shown inFig. 2 in orderztoreinforce and strengthen the bottom of thefheel section. The bottom ofthe: heel section is also provided with a plurality of perforations 18 which are adaptedto receive sharpened calks or spurs 19 which project.downwardly through the perforations '18 as shown in Fig. 3. The calks or-spurs 19 are made hollow as shown in Fig. 7 in order that they may be light although of comparatively large diameter. :Each calk or spur is provided with a head 20 which mayrest against the upper surface of the bottom of'the heel section as shown in Fig. 3. The-forward claims appendbottom plate of the heel section.

edge of the heel section is provided with inwardly bent fingers 21, three of such fingers being shown in Fig. 5 of the drawings. These fingers co'riperate with a removable plate 22 to hold the calks in position in the perforations 18. The plate 22 is provided with a transverse depressed rib 23 which is shown in F ig. 3 and strengthens the plate and prevents bending of the same. The forward edge of the plate 22 is bent downwardly and then upwardly as shown at 24 inord'er to provide a square edge the fingers 21 to hold the forward edge of the plate 22 in position on top of the calks. The side and rear edges of the plate 22 are bent downwardly as shown at 25 in Fig. 5. The plate 22 is provided further with a circular depressed portion 26 which has extending thereacross a slot 27 which slot is adapted to receive a locking key 28, which key is provided in its upper surface with a slot 29 in which a screw driver may be inserted to turn the key from its position in alinement with the slot 27 to a position transversely of the slot. The key 28 extends through the bottom plate of the heel section and its lower end is formed into a head 30 which prevents removal of the key but permits rotation of the key on the heel section. The top surface is flush with the upper surface of the plate 22 as will be apparent from Fig. 3 of the drawings. The depressed ribs 16, 17 and 23 extend toward each other but are of less depth than the thickness of the head 20. The depressed ribs 16, and 17 therefore do not contact with the plate 22 and the depressed rib 23 does not touch the Likewise the downwardly turned edges 25 of the plate 22 do not contact with the bottom plate of the heel section. This is necessary in order that the plate 22 may bear firmly against the heads of the calks. Along the forward edge of the heel section is formed a hinge portion 31 whichcooperates with a similar hinge portion on the instep section 32 of the sandal. .The heel and instep sections are there fore yieldably or flexibly connected. The instep section is shaped as shown in. Fig. 2 and is provided with upwardly bent ribs 33 and 34 which extend longitudinally of the section and reinforce the same; The edges of the instep section are bent upwardly as shown at 35 in Fig. 1 and then inwardly as shown at 36 in Fig. 3. These bent over portions of the instep section also serve to reinforce the same in order to provide a rigid section. Extending across the rear portion of the instep section and confined beneath the bent over edges 36 is a small plate 37 whose forward edge is bent upwardly as shown at 38 in Fig. 3. The plate 37 has two longitudinally extending grooves 39 formed therein which grooves are adapted to occommo'datethe rear ends of the ribs 33 and to cotiperate with 34. Adjacent the edges of the plate 37 are formed reinforcing ribs 40 which ribs 40 lie adjacent the edges 36. The grooves 39 and ribs 40 stiifen the plate 37 so that the plate will coiiperate with the instep section 32 to form a rigid structure at this point of the sandal which is usually subjected to the greatest strain. The hinge 31 permits relative movement between the sections 11 and 32 and will prevent breaking at this point. i

The instep section has its forward portion provided with a number of perforations 18 which are adapted to receive calks or spurs 19 such as described above. These calks are maintainedin position within the per-' forations by means of a removable plate 41 which extends beneath the edges 36 and is held in position by means of a key 28 similar to that described above. The rear edge of the plate'41 extends beneath the upwardly turned edge 38 of the plate 37. Edges 36 and 38 and the key 28 serve to hold the plate 41 and the calks in position on the section 32.

Pivotally connected to the forward edge of the instep section 32 by means of a transversely extending hinge 42, is a ball section 43. This ball section is provided with upwardly extending transverse ribs 44 which strengthen and reinforce the section. The section is also provided with perforations 18 to receive calks 19. The edges of the section 43 are bent upwardly as shown at 45' in Fig. 4. Aportion of each edge is cut away and then bent inwardly to form an inwardly extending edge 46 as shown in Fig. The remaining portion of each edge extends upwardly some distance and is then bent through the eyelet 47, downwardly as shown at 48 and inwardly as shown at 49 in order to provide an inwardly extending edge which cooperates with the edge 46 to hold the removable plate in position. This plate 50 is provided with depressed ribs 51 which stiifen the plate andprevent bending of the same. 'The plate 50 is provided with a depressed portion and slot adapted to receive a key 28 such as described above. The edges 46 and 49 and the key 28 serve to hold the plate and the calks in position on the ball section 43. 1 I

Pivotally connected to the forward edge of the ball section by means of the hinge 52 is a toe section 53.' This toe section is formed of asingle piece of material having its edges bent upwardly as shown invthe drawings. The section will, of course, be shaped to fit the toe of the shoe. Near the rearend of the section is .provided an upwardly extending ear 54 which is bent through an eyelet 55 to which one leg 56 of a forked strap 57 is attached. The other leg 58 of the strap is suitably secured to the eyelet47- on the ball section. 7 Q v In order that the toe section may be more securely attached to the shoe and in order that means may be provided for protecting the toe of the shoe a toe piece 59 is provided. This is shaped as shown in the drawings and may be secured to the upwardly turned edges of the section 53 by means of rivets or preferably by being spot welded thereto. Within the toe iece59 there-isfprovided an inwardly bent nger'60 as shown in Fig. 3. This finger engages the forward edge of a removable plate 61 which is shaped to fit the toe section and cover the calks as shown in Fig. 3. The edges of the plate 61 are bent downwardly as shown at 62 except where the plate engages the finger 60. At this point the edge of the plate extends horizontally in order that it may more securely engage beneath the finger 60. The plate'61 is provided with two transverse depressed ribs 63 and 64 and two longitudinally extending depressed ribs 65 and66. The ribs 63 and 64 strengthen the-plate a-gainsttransverse bending and the ribs 65 and 66 reinforce the plate adjacent the finger 60. The plate 61 is also provided with two depressed rib portions having slots27 adapted to receive keys 28 which cooperate with the finger 60 to hold the plate 61 in position on the section 53. The bottom portion of the toe section 53 is provided with a transversely extending rib 67 which forms a strengthen ing rib for the bottom plate. The downwardly turned edges 62 of the plate 61 are spaced a slight distance from the bottom plate of the section 53 so that theremovable plate 61 will bear firmly against the heads of the calks and the plate 61 will not be supported bythe downwardly turned edges 62. Likewise the ribs 63, 64, 65 and 66 do not engage the bottom plate of the toe section.

From what has been described it will be apparent that I have provided a flexible metallic sandal which may be attached to the exterior of the shoe of the wearer and in which'the calks or spurs may be-readily removed after they become dull or worn out. \Vhen it is desired to remove or change the calks in the heel section it is only necessary to turn the single key 28 of theheel section whereupon the plate 22 maybe readily removed. New calks can be'inserted and the plate again locked in position by turning the key 28 a fourth of a turn. Then it is desired to change the calks in the instep section the single key 28 formed thereon may be turned until it extends longitudinally of'the section. The slot 27 in the plate 41 extends longitudinally of the section as will be clear from Fig. 3. The plate 41 may then be slid forwardly from beneath the edges 36 and 38 and the calks removed. The reverse operation will, of course, be necessary to replace the plate 41. When it is desired to remove the calks of the ball section 43 the key 28 of this section will be turned until it extends transversely of the sandal and is in alinement withthe slot,27. The middle portion ofthe plate 50 may then be bent upwardly beyondthetop of'thekey and the plate can then be slid backwardly from beneath the .edges 46 and 49. WVhen'it is desired to remove the .plate 61 of the toe section the keys 28 thereon will be turned until their heads extend transversely of the'sandal and are in alinement with the transversely extending slots inthe plate 61. The forwardedge of the plate 61 will then be lifted upwardly and the plate drawn out from beneath the finger 60. The reverse operation will, of course, be necessary to replace the plates 50 and 61.

Inasmuch as all of the plates are reinforcedby means of ribs and asthe calks 19 are made hollow it will be apparentthatthe sandal although it is made of metal, will'not be heavy. It-may be readily attached to the foot of the wearer by means of the two straps Y15 and 57. The toepiece 59'will protect the toe of the shoe and the hinges 31, 42 and 52 will permit .theseveral sections of the sandal to conform tothe movements of the foot of the wearer. The locking plates for the calks may be easily removed-by turning the keys by means of an ordinary screw driver or a similar implement.
